Abstract
Angiography remains the gold standard in the preoperative evaluation of complex pulmonary blood supply in patients with pulmonary atresia, ventricular septal defect, and major aortopulmonary collateral arteries. In neonates, balloon occlusion aortography using a Berman balloon catheter is a very effective technique. However, in older patients this method is frequently limited due to failure to achieve distal balloon occlusion. A novel technique using a balloon valvuloplasty catheter and a standard angiographic catheter in combination is described. The technique allowed enhanced visualization of the complex anatomy in three patients scheduled for surgical intervention.
